Application filed July 26, 1907. Serial No. 385,707.

'Be'it known that I, citizen of the United Aberdeemin the VILFRED BAKER,a States, residing at county of Brown and State This invention relatesto loading devices of that general class in which a wagon is providedwith a box, or receptacle. and has have invented a new and usefulLoading Apparatus, of which the fol-' lowing is-a specification.

at the front end a fork arrangedto gather up shocks, hay, fodder orthelike, the same into the box or receptacle without wagon,

One ofthe principalobjects of the in- 'vention is to operating mechanismin, which the liftng powerpis at. the maximum at the startthe speed oftravel of the fork creasestoward the limit of discharging movement'toinsurerapidity of operation and to more effectively toss the shock orother' material backward into the receptacle;

A further object of the invention is to I provide an improved forkoperating mechanism which may be readily controlled by p the driver orother attendant and which is soar-ranged as to be automatically disconnecte'd when the fork has reached the limit of its discharging movement,so-that danger ,of breakage or" strain of the parts'is prevented.

and toss provide an improved form of mg of the lifting movement, and inwhich gradually in- 1- A; still -further'object of the mast is.

to simplify and improve the construction and arrangement of the machine,in'ord'er that the latter may be more readily controlled by, theoperator and'to place the steering fork actuating and brakingjmeans insuch manner as tobe most convenient for the operator. J

\Vith these and other will more fully hereinafter appear, the 'in-,vention consists in certain novel features of constructionand'arrangerhent of parts, here inafter-fully described, illustrated inthe accompanying drawings, and particularly pointed out in the appendedclaims, it beobjects in view, as-

. ployed to ing understood that various chapges in the form,proportions, size and minor'detailsof the structure may be made withoutdeparting from the spirit or sacrificing any of the advantages of theinvention;

Similar numerals of reference are emthroughou ings.

The main frame comprises sills or bars 10 which are connected at theirrear ends by a cross bar 11, and at an approximately central point by across bar '12, and suitable braces 13 maybe added for the purpose ofstrengthening and bracing the structure.

'Near the rear end of the frame are journal the several figures 'of thedrawboxes for the-support ofa rear axle 15 on indicate correspondingparts,

which are secured wheels 16, and at the front of the frame are arrangedvertical casings 17 in which are mounted vertical spindles 18, the lowerends of which are turned outward to form journals for the support of thefront wheels '19. dies are provided with rearwardly extending'rockerarms 20 that are connected by a link 21, and extending from this link isanarm 22 car ing a double foot rest 28 that is arranged immediately infront of and be low the operators seat 2-1, -By exerting pressure on thefoot rest the vehicle'may be steered in any desired course. The braces13 which-form a. part of thefrarne are preferably arranged bar orbrace12 to the lower-ends of the eas- The spinto extend from the cross ings17, these casings having suitably-in- 'clined. 'sockets 26 for thereception of ,the outer eiid's of the brace members.

The load receptacle-or box 29 is hinged at 30 to the-rear cross bar 11,the point of connection being somewhatto the rear of the longitudinalcenter. of the., .box, so that the latter rnaynormally-rest in .ahorizontalposition .on' the, ;frame,z

ytb syee mn bna and it. may be lo k d.--

' reinforced bybrace bars 69 oted to the forward end of the box andarranged to engage a pin or lug 32 that is carried by the cross bar 12.At-the lower rear end of the box or receptacle is a cross plate or board33 that is inclined approximately at an angle of 45 to the bottom of thereceptacle, and which will rest practically flat on the ground when thereceptacle is moved to dumping position, as shown by dotted lines inFig. Above this cross plate or bracket 44 on one of the frame bars 10.As

a result of this construction, the tilting upward of the front end ofthe receptacle during the dumping operation will operate throughvthechain or cable 41 and the links to move the end gate to open position.

Secured to, the lower edges of the frame bars 10 are blocks 50 throughwhich extend bolts 51 forming pivotalsupports for the rear carrying bar52 of a rake 53. The rake is provided with forwardly projecting arms'54: which are connected by a cross bar 55 to the ends of which areattached lifting cables 56, there being one of such cables at each sideof the rake. At a point slightly in adv'ance of the forward end of thereceptacle the frame 10 is provided with a pair of standards 60 whichare securely held in )lace, and'the upper ends of which are rigidlyconnected by a tube 61. Through this tube extends a shaft 62 that isprovided near its opposite ends with peripherally grooved snails 63, theouter ends of which are reinforced by side links 64:. To the 'in herrings of the snails are attached the ends of the -lifting cables 56, andas the snails are turned, the cables are wound thereon with graduallyincreasing speed, so that the lifting movement of the fork progresses atgradually increased speed from the load receiving to load dischargingposition.

Mounted loosely on one end of the shaft 62 is a sprocket wheel 65, andthe adjacent faces of the sprocket wheel and snail hub are provided withclutching teeth 66, provision being. made for moving the sprocket wheelto snail engaging and releasing position. The cables 56 are guidedaround suitable sheaves 67 that are carried by vertical osts orstandards 68 extending upward rom the frame 10, andthese are preferablythat extend, also, to the posts 60. 1

Connected to the shaft 15 by means of compensating gearing 70 is a gearwheel 71 sprocket wheel 65 'will be continuously roand said fork isconnected to the rocker arm which intermeshes with a pinion 72 that iscarried by'a stud shaft mounted in a short bracket 73 extending from oneside of the frame. This shaft, also, carries a sprocket wheel 74 that isconnected to the sprocket wheel 65 by a link belt 7 5 and said link beltis held in engagement with the sprocket wheel 7 f by a small idler 76,so that the tated so long as the'l'oading apparatus is driven forward.The outer portion of the hub of sprocket wheel 65 is provided. with anannulargroove that receives a fork 7 8,

79 on the upper end of an approximately vertical shaft 80. The uppenportion of this shaft is guided through a strap 81 that is fulcrumed onthe end of the shaft 62, and its lower end is guided, by a bracket 82that projects from one ofthe standards 60. The lower end of the shaftcarries a crank arm 83 from which extends a link 84, and

from said link extends a second link 85 (Fig. 6) that projects beyondthe inner edge of the frame bar 10 and is disposed in the path ofmovement of an arm 85 on the rake,

"so that as the latter nears the completion of its load dischargingmovement the arm will engagethe link and transmit movement/.g throughthe crank 83, the shaft 80, rocker e5 arm 79, and fork 78 to thesprocket wheel 65, thereby moving the sprocket wheel from i engagementwith the snail'and automatically unclutching the fork operatingmechanism.

The link 84: is connected by a link-88 to a hand lever 89 that isfulcrumed on a bracket 90 within convenient reach of the operator, sothat the latter may readily clutch the sprocket Wheel to the snail,whenever it is desired to discharge the load received by the fork.

The inner hub of one of the snails 63 is in the form of afriction drumor disk 90' that is encircled by a band brake 91 (Fig. 5). 1 One end ofthe hand brake is connected to a vertically disposed rod 92 that isguided by upper and lower brackets 93-434, and between the lower bracketand a collar 95 the rod is arranged a helical compression spring 96 thattends to normally hold "the brake in releaseposition; The lower ,end ofthe rod is connected to a crank-9Tfthat is carried by a shaft 98journaled in abracket or hanger 99 carried by one of-the frame 120members 10. This shaft extends inward and to its inner end is secured alever 100having an approximately horizontal arm 101 that fits againstthe back of the operator, so that the latter byleaning backward mayapply the brake in order to check the movement of the fork. Secured tothe fork is a pair of spring arms 102, which, at the completion of theupward movement of the fork come into contact with the tube 61 and checkthe movement without arresting the move- 130 103 to which is connectedthe forward end of a spring 104. The rear end of the spring Isprocketwheel by ment ofthen-shock the latter will be tossed rearwardinto the receptacle. in orderto assist the return movement of the fork,the crossbar 52 is provided with a rearwardlyextending arm is connectedby a cross bar 11'.

A modification of themeans for transmitcable or chain 105 tothe -ting mvement from the rear wheel shaft is shown in Fig-7. Inthis case thewheel 71 is in the nature of a sprocket wheel, and the link belt-75 engaes directly therewith and is held against tie lower portion ofthesuitable idlers 107,

It will be seen that the Operating portion of the fork is of a widthapproximately equal to that of the receptacle, while the carryingportion of the fork is comparatively narrow. This permits the locationof the seat inside the frame so. that the fork may be swung to and froover the seat.
